The CSNULL series of cable assemblies features the same construction as the CSMN series but are wired to the most common null modem wiring schemes. The transmit data and receive data signals are crossed to allow two DTE or DCE devices to communicate. All assemblies utilize 26 AWG stranded conductors with foil shielding for flexibility and performance. Backshells are fully molded with copper shielding for better immunity to EMI/RFI. Mating hardware is 4-40 thumbscrews which makes securing without tools quick and easy.
